Effect of liquid waste addition on the overall performance of anaerobic bioreactor landfill
… liquid wastes on the overall performance of anaerobic bioreactor landfills is not known. In this study three different liquid wastes were added to mix of office paper, newspaper, cardboard and plastic in 3 different concentrations under anaerobic conditions to determine their effect on …

Effect of sugar waste, surfactant waste and paint waste on the degradation of anaerobic bioreactor landfill components
Anaerobic bioreactor landfills are the landfills with an increased moisture content in order to achieve a better biodegradation. Many Bioreactor landfills accept outside liquid wastes to achieve a higher moisture content . But the effect of these wastes on the degradation of landfill components is …

Performance and Mechanisms of Excess Sludge Reduction in the Cannibal™ Process
… activated sludge systems incorporating an anaerobic bioreactor into the sludge recycle stream were operated. In this study, the solids production in the Cannibal system was about 35-40% of the conventional system under steady state conditions. The reduction in waste sludge was optimized …

Increased Anaerobic Digestion Efficiency via the Use of Thermal Hydrolysis
Waste sludge is frequently treated by anaerobic digestion to kill pathogens, generate methane gas and reduce odors so the sludge can be safely land applied. In an attempt to reduce sludge volumes and improve sludge dewatering properties, the use of thermal hydrolysis (TH), a sludge pretreatment …

Developing a Mechanistic Understanding and Optimization of the Cannibal Process: Phase II
… sludge process integrated with a side stream anaerobic bioreactor, is capable of reducing excess sludge up to 60% compared to the conventional activated sludge process. The hydraulic retention time (HRT) in the Cannibal bioreactor and the interchange rate (the percent of sludge by mass …

Facultative Bioreactor Landfill: An Environmental and Geotechnical Study
… of Municipal Solid Waste treatment is known as bioreactor landfill technology. Bioreactor landfills are sanitary landfills that use microbiological processes purposefully to transform and stabilize the biodegradable organic waste constituents in a shorter period of time. One of the most popular …

The Biological Sludge Reduction by anaerobic/aerobic cycling
… sludge system that incorporates a sidestream anaerobic bioreactor, called the Cannibal process, was the focus of this study. A prior study of this process (Novak et al., 2007) found that this system generated about 60% less solids than conventional activated sludge without any negative effects …

Evaluation of pollution potential and bioremediation of tannery-based chromium wastes in Sub-Saharan Africa: the case of dump sites in Beit Ore Tannery in South Africa and Dogbone Tannery in Kenya
… (VI) polluted soils. It further investigated the anaerobic bacterial profile of donkey dung assisted anaerobic bioreactor remediation of tannery based chromium wastes. Preliminary study of the use of donkey dung as a sorbent for Cr (VI) sequestration was also performed. This study was carried out …
